1. Thermal Expansion

A. Copper (for example)

Initial Temperature, [please get the reading in Multi-meter and use

calibration factor to convert it into ]

Initial Length,

Final Temperature, [similar like above]

Elongation,

Use the formula for thermal expansion,

Also use the formula to find the error,

B. For Aluminum/Steel [Do similarly]

2. Charles’ Law

We know the volume of a cylinder is, . As during this process, only height is

changing, therefore, we can conclude that

Therefore we can write the relation of Charles’ Law for this experiment as follows:

where is a proportionality constant.

If the dependence between the height

h

of the cylinder and the temperature

T

is linear,

then the Charles’ Law is verified.
